We have AC in our gym, but for the last week it has been about 95 to 99 degrees with a heat index of 105. Plus, major humidity. If you are from the south, you know that means when you walk out the door within five minutes you are pouring with sweat. Therefore, the AC has been working double time here and the gym is just an aluminum building with no insulation. The coaches thought it wasn't working correctly, so they had the Heating and Air people come out. They said it was working properly, but it just couldn't keep up with the heat.
The gym has several big fans and has purchased another one. The booster club bought a misting fan for the girls to use outside during breaks that they take about every hour. Our girls were told to bring frozen water, as well.
You may want to check your local Fastenal for some headbands that my dd's wear around their necks. You wet the bands and tie them around their necks. Construction workers tie them around their foreheads.When you wet them, they have stuff in them that keeps them really cool. We used them at Disney World a few weeks ago, also. They stay cool for about 24 hours, then just rewet them and they are ready to use again. They are like $4.00, so very inexpensive.
